Using MFA Verification Methods Other Than Salesforce Authenticator

1. Prepare the MFA verification method you intend to use. If using a one-time password (OTP) generator app, install it on your mobile device.
2. Log in to Salesforce using your username and password in a desktop browser.
   
3. When the "Choose a Verification Method" screen appears, follow the steps below (starting from 3-1) based on your chosen method.
   Note: Depending on your organization's settings, the screen for the highest-priority verification method enabled in your org may appear directly. To use a different method, click [Choose Another Verification Method] at the bottom of the screen to return to the selection menu.
